N155 is an upper division class aimed at Biological Sciences and Neurobiology Majors. It requires N110 or N152 as a prerequisite. The format of the course consists of brief introductory lectures and class discussion of primary research articles. All students are required to read assigned research articles and reviews for each class and discuss them in a Journal Club format. Small group discussion, critical analysis of primary literature, oral presentations, and written analyses of research papers are few of the skills that are encouraged and developed in this course as we analyze basic mechanisms of development and relate them to deficits that can lead to complex developmental disorders. Specific topics that are covered include: neuronal specification, neuronal migration, guidance of nerve processes to their targets, and the formation and maintenance of synaptic connections.

No textbook is required. However, through reading of articles, research performed in multiple vertebrate and non-vertebrate species and its relevance to humans are discussed.  Class size is typically between 20-25 students.


Topics covered include:

Neuronal specification and patterning

Neuronal migration (excitatory and inhibitory neurons)

Neuronal migration and developmental disorders

Growth cones and pathfinding mechanisms

Axon branching and synapse formation

Dendritic branching –  self avoidance mechanisms

Synapse formation and synaptic competition

Synaptogenesis and neurodevelopmental disorders
